The Government seeks 2 each of NSN 7R-1680-016216684-EY, with delivery FOB Origin, but it does not own the data or rights needed to contract repair from additional sources and has determined buying the data or reverse engineering the part is uneconomical. The item is flight critical and/or lacks adequate technical data for full and open competition, so Government source approval is required before contract award and only previously approved sources were solicited. Non-approved sources must submit the information required by the applicable NAVSUP WSS Source Approval Information Brochure (Spares or Repair) with their offer; offers missing required source approval data will not be considered. The intended contract action is sole-source under FAR 6.302-1, though responsible sources may identify their interest and capability, and FAR Part 12 commercial item procedures are not being used. Award will be made only if the offeror, product/service, or manufacturer meets qualification requirements at award, and if source approval cannot be processed in time, award may proceed based on Fleet support needs.
